FUEL SAVER.

Application filed March 10, 1922. Serial No. 542,775.

To all whom it may concern:

Be it known that 1, CHARLES E. NORD- QUIST, a citizen of the UnitedStates, residing at South Gonnellsville, in the county of Fayette andState of Pennsylvania, have invented certain new and useful Improvementsin Fuel Savers, of which the following is a specification.

The present invention relates to fuel savers having for its principalobject to provide a mechanism for heating the water before the same isdelivered to the boiler thereby lessening the consumption of fuel.

. Another object of the invention is to provide a device of this naturewhich will be of extremely simple, durable and inexpensive construction,one which is efficient and reliable in operation, and well adapted tothe purpose for which it is designed.

With these and numerous other objects in view, the invention resides incertain novel features of construction, and the combination andarrangement of parts as will be hereinafter fully described and claimed.

In the drawing I Figure 1 is in an elevation of the apparatus showingthe parts assembled,

Figure 2 is a longitudinal section through the Y-connection and itsassociated parts,

Figure 3 is a transverse section taken therethrough on the line 33 ofFigure v2 looking in the direction of the arrow,

Figure 4 is a perspective of the nipple, and

Figure 5 is a perspective of the nozzle.

Referring to the drawing in detail the numeral 1 designates a portion ofa boiler steam pipe connected to the outlet extremity of a heatingdevice generally denoted by the numeral 2 which consists of a body 3 anda branch 4. The ends of the body 3 are provided with} external threadsso that one end thereof may be attached to the inlet end of .the feedpipe 1 and the other end receive a nipple 5.

This nipple 5 has extending exteriorly from its body portion a pair ofdiametrically opposed wings 6 with which a suitable tool may be engagedfor turning the nipple. A threaded bore extends through the nipple andis enlarged at its inner end and this inner end is also provided withexternal threads so that the nipple may be attached to the end of thebody 3 as shown in Figure 2. The steam pipe 7 is connected with the boreof the nipple 5 while a nozzle 8 is threadedly connected to the enlargedportion of the nipple. This nozzle comprises a body portion having abore extending longitudinally therethrough which tapers toward theintermediate portion thereof. A flange 9 of annular construction isarranged about the intermediate portion of the nozzle and externalthreads 10 are situated to one side of this flange 9 so that the samemay en-- gage the internal threads of the enlarged bore of the nipple 5.It is to be noted that the mouth of the nozzle 8 is so situated as toterminate adjacent the entrance of the branch 4 into the body 3 of theY-connection 2. A water pipe 11 is attached to the branch 4 and as thewater is delivered through the branch the steam will be deliveredthereto immediately for heating the same before it actually enters theboiler feed pipe 1. It is my purpose to heat the water to a few degreesbelow the boiling point before the same actually reaches the boiler.

The radiator 1 is, of course, disposed adjacent the boiler and a smallamount of heat will be dissipated by the radiator but this will benegligible from a practical standpoint. The radiator gives the steam achance to mix with the water as the steam and water pass therethroughand thus gives the water an opportunity of becoming heated before itreaches the boiler. The usual practice is to inject the steam into thewater immediately before the same enters the boiler and thus the steamdoes not have an opportunity of heating the water to any great extent asis the case with the apparatus herein described. v

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the device willbe readily understood without a more extended explanation.
